The three options that will not be in your audit trail are A, C, and H. These options are either not relevant to the information security of ABC's healthcare mobile app development, support, and lifecycle process, or not within the scope of your audit. The amount of money that residents' family members pay to install the app (A) and the number of users of the app are not related to the information security aspects or objectives of the ISMS1. The verification of the developer's certifications (H) is not your responsibility as an ISMS auditor, as you should rely on the competence and impartiality of the certification bodies that issued them2. The other options are relevant and within the scope of your audit, as they relate to the security functions, testing, policies, and procedures of the mobile app development, support, and lifecycle process13.

Conducting an ISO/IEC 27001 audit

* B. This clause requires the organisation to determine the interested parties that are relevant to the ISMS, and the requirements of these interested parties12. This clause is relevant to the verification of the scope of the ISMS because it helps the organisation to identify the stakeholders that have an influence or an interest in the information security of the organisation, such as customers, suppliers, regulators, employees, etc. The organisation should also consider the needs and expectations of these interested parties when defining the scope of the ISMS, and ensure that they are met and communicated.
* E. This clause requires the organisation to establish an information security policy that provides the framework for setting the information security objectives and guiding the information security activities13. This clause is relevant to the verification of the scope of the ISMS because it helps the organisation to define the direction and principles of the ISMS, and to align them with the strategic
* goals and context of the organisation. The information security policy should also be consistent with the scope of the ISMS, and should be communicated and understood within the organisation and by relevant interested parties.
* F. This clause requires the organisation to determine the internal and external issues that are relevant to the purpose and the context of the organisation, and that affect its ability to achieve the intended outcomes of the ISMS14. This clause is relevant to the verification of the scope of the ISMS because it helps the organisation to understand the factors and conditions that influence the information security of the organisation, such as the legal, technological, social, economic, environmental, etc. The organisation should also monitor and review these issues, and consider them when defining the scope of the ISMS.
* H. This clause requires the organisation to determine the boundaries and applicability of the ISMS to establish its scope15. This clause is relevant to the verification of the scope of the ISMS because it helps the organisation to describe the information and processes that are included in the ISMS, and to document the scope in a clear and concise manner. The organisation should also consider the issues, requirements, and interfaces identified in clauses 4.1, 4.2, and 4.3 when determining the scope of the ISMS, and ensure that the scope is appropriate to the nature and scale of the organisation.

Explanation:

* Risk analysis is the process by which the nature of the risk is determined along with its probability and impact. Risk analysis involves estimating the likelihood and consequences of potential events or situations that could affect the organization's information security objectives or requirements12. Risk analysis could use qualitative or quantitative methods, or a combination of both12.
* Risk management is the process by which a risk is controlled at all stages of its life cycle by means of the application of organisational policies, procedures and practices. Risk management involves establishing the context, identifying, analyzing, evaluating, treating, monitoring, and reviewing the risks that could affect the organization's information security performance or compliance12. Risk management aims to ensure that risks are identified and treated in a timely and effective manner, and that opportunities for improvement are exploited12.
* Risk identification is the process by which a risk is recognised and described. Risk identification involves identifying and documenting the sources, causes, events, scenarios, and potential impacts of risks that could affect the organization's information security objectives or requirements12. Risk identification could use various techniques, such as brainstorming, interviews, checklists, surveys, or historical data12.
* Risk evaluation is the process by which the impact and/or probability of a risk is compared against risk criteria to determine if it is tolerable. Risk evaluation involves comparing the results of risk analysis with predefined criteria that reflect the organization's risk appetite, tolerance, or acceptance12. Risk evaluation could use various methods, such as ranking, scoring, or matrix12. Risk evaluation helps to prioritize and decide on the appropriate risk treatment options12.
* Risk mitigation is the process by which the impact and/or probability of a risk is reduced by means of the application of controls. Risk mitigation involves selecting and implementing measures that are designed to prevent, reduce, transfer, or accept risks that could affect the organization's information security objectives or requirements12. Risk mitigation could include various types of controls, such as technical, organizational, legal, or physical12. Risk mitigation should be based on a cost-benefit analysis and a residual risk assessment12.
* Risk transfer is the process by which a risk is passed to a third party, for example through obtaining appropriate insurance. Risk transfer involves sharing or shifting some or all of the responsibility or liability for a risk to another party that has more capacity or capability to manage it12. Risk transfer could include various methods, such as contracts, agreements, partnerships, outsourcing, or insurance12. Risk transfer should not be used as a substitute for effective risk management within the organization12.

Leaving the cabinet unlocked while the technician is on a lunch break exposes the client's equipment and data to potential physical security risks, such as theft, damage, or tampering. This is a violation of the ISO/IEC
27001:2022 requirements for physical entry (control 7.2) and physical security monitoring (control 7.4), which aim to prevent unauthorized access to information processing facilities and assets. Therefore, the appropriate actions for the auditor are:
* Raise an opportunity for improvement (OFI) suggesting that the cabinet doors are locked whenever clients leave their suites, even if they intend to return within a short time. This would enhance the security of the client's equipment and data, and reduce the likelihood of security incidents.
* Review the CCTV records to ensure that only the client has accessed the cabinet since it was last confirmed as locked. This would verify the integrity and availability of the client's equipment and data, and identify any possible unauthorized access or interference.
* With the permission of the guide, speak to the customer to confirm that they are in the process of swapping out a drive. This would validate the reason for leaving the cabinet unlocked, and assess the impact and risk of the activity on the client's information security.
